Answer:
y = x + 3.1
Step-by-step explanation:
As we move from (-8.3, -5.2) to (6.4,9.5), the horizontal change ("run") is 14.7 and the vertical change is 14.7. Thus, the slope is m = rise / run = 14.7 / 14.7 = 1.
Write out y = mx + b. Because m = 1, we have
9.5 = 1(6.4) + b, or 9.5 = 6.4 + b, with the result that b = 3.1
and so the desired equation is y = x + 3.1

The mystery number is a three-digit number. Its digits are 3, 6, and
2.
• The 6 has a digit on its left and on its right.
• The 2 is not the last digit.
What is the mystery number?
Answer:
263
Step-by-step explanation:
Let the number = xyz
The 6 has a digit on its left and on its right. It must be the middle number.
y = 6, so the number is x6z.
The 2 is not the last digit. It must be the first digit.
x = 2, so the number is 26z.
The remaining digit — 3 — must be the last digit.
z = 3, and the number is 263.
The mystery number is 263.
What is a word problem?A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.
For the given situation,
Let the three digit number be xyz.
The digits are 3,6,2.
The mystery number can be found as
The 6 has a digit on its left and on its right, so the number becomes [tex]x6z[/tex].The 2 is not the last digit, so the number becomes [tex]26z[/tex]The left number is 3. Thus the number becomes [tex]263[/tex].Hence we can conclude that the mystery number is 263.

Between 1998 and 2018, inflation for prices of goods and services has been about 51%. Suppose a salon charged $18 for a basic haircut in 1998 and has been raising prices by a steady percentage each year to keep up with inflation.
Answer: $22.12
Step-by-step explanation:
I just did the compound interest formula which is
starting amount * (1. interst rate) ^ number of years
example if you have 100$ and you want to know how much it is worth if it appretiates by 7% of a period of 20 years it would look something like this;
100 * (1.10) ^20 = 672.74$
but since you have to figure out what it was in 2008 which was exactly half way in the period you divide the exponent by half so your formula should be;
I know the answer is right because I asked my teacher and it's correct.
REAL EXAMPLE: 18 * (1.51) ^.5 = 22.12$
The amount should be $22.12.
Important information:Between 1998 and 2018, inflation for prices of goods and services has been about 51%. Suppose a salon charged $18 for a basic haircut in 1998calculation:[tex]= 18 \times (1.51) ^{.5}[/tex]

Answer:
2x - 5
Step-by-step explanation:
2x^3 + 4x = 2x(x^2 + 2)
-5x^2 - 10 = -5(x^2 + 2)
so the factors are (2x - 5)(x^2 + 2).

What type of graph would you use to compare the prices of Felix's books and of Tyler's books? In two or more sentences, explain your choice.
bar graph
line graph
scatter plot
histogram
box-and-whisker plot
Felix's books
Mean 10.21
Median 6
Mode 3
Range 26
Tyler's Books
Mean 77.36
Median 68
Mode 76
Range 92
Answer:
I would use box-and-whisker plots to compare the two sets of prices. The plots will show the ranges, which is the difference least and greatest data points. Also, the medians will divide each set of data into 4 equal groups. Comparing these middle values and range of prices in each group will show how similar the prices are.

It’s starting to get colder at night, so Sam decides to remove the goldfish from the pond in his backyard. He tries to catch the fish with a net; however, even though he can clearly see the fish in the water, he misses it. He infers that he missed because the light is being refracted. What is causing the refraction?
1: The air and the water are different colours.
2: The air and the water have different densities (and media).
3: The water is reflecting the light.
4: The air is reflecting the light.
EXPLAIN YOUR ANSWER
Answer:
Light refracts whenever it travels at an angle into a substance with a different refractive index (optical density). This change of direction is caused by a change in speed. For example, when light travels from air into water, it slows down, causing it to continue to travel at a different angle or direction. Which would make him see the fish in a spot that its not at. So 2 is the correct answer.

We gave a national verbal proficiency test that has a mean score of 500 with a standard deviation of 75. What raw score would correspond to the 60th percentile
Answer:
519
Step-by-step explanation:
Let's assume that the scores for the national verbal proficiency test follow a normal distribution.
Mean score (μ) = 500
Standard deviation (σ) = 75
According to a Z-score table, the score for the 60th percentile is roughly z = 0.253
For any score "x", the z-score is given by:
[tex]Z=\frac{X-\mu}{\sigma}[/tex]
For z = 2.53:
[tex]0.253=\frac{X-500}{75}\\X=519[/tex]
The raw score to the 60th percentile is 519.

. A don Alvaro le encargaron construir un depósito de agua de 729 m3 ¿Cuánto debe medir la arista del depósito?
Answer:
a = 9m
Step-by-step explanation:
You can take the volume of the water tank as the volume of a cube.
The volume of a cube with side a is given by:
V=a*a*a = a^3
To find the value of a you do a the subject of the formula:
a=(V)^{1/3}
You replace and obtain for a:
a = (729m^3)^{1/3} = 9m
hence, the rim a of the water tank is 9m
Answer: The side of the tank is 9 m.
Step-by-step explanation: A water tank is normally a cube, which means length, width and height has the same measure.
To calculate Volume of a cube:
V = length*width*height
Knowing that volume is 729 and assuming sides are x:
x*x*x = 729
x³ = 729
x = [tex]\sqrt[3]{729}[/tex]
x = 9
The volume is in cubic meters, so sides of the tank measures 9 m.
What number can be added to the right side of the equation to change it to a function with one real zero
Answer:
+3
Step-by-step explanation:
Where the graph crosses the x axis is where the real zeros exist. The parabola's minimum is at point (-3,-3) by adding a +3 to the right side of the equation will raise the minimum to point (-3,0) therefore giving it only one point where it touches the x axis. Then the parabola will only have one zero, the minimum of the parabola.
